SAP-RECEIVING RECEPTACLE AND APRON.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed February 8,1907. Serial No. 356,364.

To aZZ whom it may concern.-

Be it known that I, FRANK RUDOLPHI, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Sap-Receiving Receptacles and Aprons, of which the following is a specification.

My invention relates to improvements in sap receiving aprons and receptacles.

In sap receptacles and aprons heretofore in use, where the receptacle is supported on the lower longitudinal edge of the apron, the weight of the receptacle tends to tilt the inner edge of the apron upward in the cut or gash in the tree in which it is inserted so that the sap is liable to a greater or less extent to flow downward under or beneath the apron instead of on top of the same into the receptacle.

The object of my invention is to provide a sheet metal sap receptacle and an apron for supporting the same and delivering the sap from the tree thereto, of a simple, efficient and durable construction, by means of which the objections heretofore experienced may be overcome, and by which the sheet metal apron that is inserted in the cut in the sap bearing tree, will have at the ,ends thereof integral guide and supporting arms or members to engage the supporting hooks on the ends of the sap receptacle so that the weight of the sap receptacle will come upon the ends of the apron and so that thereceptacle will fit between the supporting arms of the apron, and thus be held by them from disengagement or dislodgment.

In the accompanying drawing forming a part of this specification, Figure 1 is a front elevation of a sap receptacle and apron embodying my invention. Fig. 2 is a central vertical cross section. Fig. 3 is a central longitudinal section of the receptacle. Fig. 4 is a partial horizontal section on line 44 of Fig. 3. Fig. 5 is a detail end elevation of the apron. Fig. 6 is an end elevation of the receptacle and Fig. 7 is a detail plan View showing the sheet metal blank in the flat from which the receptacle is formed.

My invention consists in the means I employ to practically accomplish this object or result as herein shown and described, and

more particularly set forth in the claims In the accompanying drawing forming a part of this specification, A represents a portion of a turpentine bearing or other sap bearing tree, in the gash or cut a of which my improved sheet metal apron B is inserted. And D is my improved sheet metal sap receptacle. The sheet metal apron B is provided with an inner or upper concavely curved edge b, the curvature preferably corresponding somewhat to the curvature of the ordinary sized sap bearing tree in the cut of which the apron is to be inserted. At its ends the apron B is provided with divergent upwardly projecting end flanges b and downturned or depending receptacle supporting arms b The depending supporting arms 6 are furnished with hooks or seats 5 to receive the supporting hooks d of the sap receptacle D, the upper edge of the hooks extending inwardly beyond the lower edge 6 of the apron B so that the upper inner edge (1 of the sap receptacle D will project under the lower edge I) of the apron and so that the overhanging lower part of the apron which fits inside the receptacle D will aid in preventing disengagement or dislodgment of the receptacle from the apron. Asthe receptacle D fits between and is embraced by the end supporting arms of the apron, these supporting arms prevent longitudinal movement of the receptacle on the apron. And as the weight of the receptacle D comes upon the ends of the apron instead of upon the lower edge thereof, it has no injurious tendency to tilt the apron upward at its upper edge. The depending and forwardly projecting receptacle supporting arms are preferably furnished with marginal integral beads 12 and b to strengthen and stiifen the same. The inner upright edge I) of the hook or seat 5 serves'as a stop orshoulder for the upper inner edge of the receptacle or of its supporting hook to abut against, and the inner edge of the upwardly projecting outer lip 12 of the hook 6 serves to hold the receptacle in place against any outward movement.

The receptacle D is preferably of a long narrow form with upright sides (1 and outwardly flaring ends d d and bottom (1, all preferably formed in one integral piece from a flat sheet metal blank D by suitable folds therein such as customarily employed in the manufacture of bread pans or other sheet metal articles of a rectangular or box-like form in horizontal section, which are made in one piece. The flaring ends 01 of the receptacle D have outwardly turned integral supporting hooks (1, one or more, preferably two, at each end of the receptacle D. The flaring ends (1 of the receptacle D also have integral locking lips d which are clenched down upon and embrace the integral angle folds d d at the integral flaring ends of the receptacle. In Fig. 7, the dotted lines (i indicate the lines upon which the blank D is folded to form the same into the one piece long and narrow receptacle D with flaring ends. The upright sides d of the receptacle D are preferably furnished with rolls or curved edges (1 to stiffen and strengthen the same.

I claim 1. In a sheet metal sap receiving receptacle and apron, the combination with a sap receiving receptacle having supporting hooks at its outer ends, of an apron having a curved upper longitudinal edge adapted to be in serted in the gash of a sap bearing tree, and

provided at its outer ends with upwardly projecting divergent integral flanges having integral depending supporting arms furnished with hooks engaging the supporting hooks of the receptacle, substantially as specified.

2. In a sheet metal sap receptacle and apron, the combination with a receptacle having supporting hooks at its ends, of an apron having depending supporting arms at its ends furnished with hooks engaging the supporting hooks on the receptacle, substantially as specified.

3. A sheet metal sap receptacle supporting apron having integral upwardly projecting flanges at the ends thereof provided with integral depending supporting arms furnished with receptacle engaging devices, substantially as specified.

4. The combination with a sheet metal sap receptacle supporting apron having integral depending supporting arms at the ends thereof of a sap receptacle fitting between said supporting arms of the apron, substantially as specified.

5. A one piece sheet metal sap receptacle having a bottom, upright sides and flaring ends, said flaring ends having integral folded locking lips to bind the integral folds of the flaring ends together, and said flaring ends having also integral supporting hooks for the receptacle, substantially as specified.

6. A one piece sheet metal sap receptacle having a bottom, upright sides and flaring ends, said flaring ends having integral folded locking lips to bind the integral folds of the flaring ends together, and said flaring ends having also integral supporting hooks for the receptacle, the upright sides of the receptacle having outwardly turned, rolled or curved edges, substantially as specified.

7. A sheet metal sap receptacle supporting apron having integral depending and forwardly projecting supporting arms adapted to engage the ends of the sap receptacle, substantially as specified.

8. A sheet metal sap receptacle supporting apron having integral depending and forwardly projecting supporting arms adapted to engage the ends of the sap receptacle, said supporting arms being provided with mar ginal stiffening beads, substantially as speci- 9. A sheet metal sap receptacle support FRANK RUDOLPIII.
